Ot er objects will be apparent as the descri tion proceeds.

The invention consists in the combination arrangement of the parts and in the details of the construction, as hereinafter set forth and claimed.

The preferred construction of the invention is exemplified with usual swimming'-v pool basin 1 comprising side walls 2 and 3, end walls 4 and 5, and bottom 6 which may be constructed of concrete, or other suitable water retaining material. The walk 7 which is shown surrounding the basin may be constructed of concrete, or other suitable material, and may be included or not in the structure, as desirable.

The usual scum gutter 8 extends completely around basin 1 and is formed in the end walls and the side walls at a sulicient distance above bottom 6 to conform with the p required depth: of the water 9 usually contained inv the basin, whereby when the level or surface 10 of water9 is slightly higher than the outer Vside 11 of the scum gutter,

the top surface of the water is adapted to drain into the gutter, thereby carrying the foreign matter such as oil, dirt, bish, and the like, pool. l

Adjacent end wall 5, of the basin, is compartment 12 comprising bottom 13, side walls 14 and 15, end walls 5 and 16, and top 17 which isflush with the top 18 of the basin.

Within compartment 12 are filtering units 19 suitably connected by pipe 20, as usual with pump 21. The filtering units, also, are suitably connected as usual with pipel 22 which leads through wall 5, or if desirable it may be carried through walls 2, 3, 4 and 5 of basin l, whereby after the water is forced, under pressure, through the filtering units it is again returned into the basin.

The water 9 is adapted to be returned to the filtering units through pipes 24 and 25, respectively, connected with scum gutter 8 and main drain outlet or pipe 26 which leads through bottom 6 of the basin. The pipe 24 is of smaller diameter than pipes 25. The opposite ends 27 and 28, respectively, of

pipes 24 and 25, are connected with A.gate

valves 29 and 30, respectively, communicating with inlets 31 and 32, respectively, of chambers 33 and 34 of krcasing 35 ofscum gutter overflow control 36.

Secured to top 37 of casing 35 and communicating with opening 38, in the casing, is reducer 39 having its upper end 40 secured, by bolts 41, to lower` end 42 of reservoir 43 having cap 44 suitably secured to itsupper end 45. Projecting through hole 46, in the cap, is tube 47 having its upper end 48 protruding through hole'17 in top 17 and flush with the top of the compartment 12. Y Y Inside reservoir 43 is a copper, or other suitable material hollow body or floatV 49 grass, rubi from the surface of the` capable of movement longitudinally inside the reservoir. Fixed to the bottom 50-of Ithe float is valve stem 51 which is maintained in position centrally of the reservoir, as by being slidably received in hole 52 in guide 53 secured in. position between ends 40 and 42,' respectively, of reducer 39 and reservoir 43. The guide 53 is webbed formed to permit the free passage of water through holes 53 from reducer 39 intoreservoir 43, and vice versa.

The valve stem may beformed in sections and secured together by means o'l'union 55, it' desirable, to facilitate in assembling the control 36. Y

Suitably secured to bottom 56 of valve stem 51 is compound valve head 57 consisting of spaced apart heads 58 and 59, suitably fixed to the valve stem. The heads 58 and 59, respectively, comprise plates 60 and 61, respectively, having ribs 62 and 63 integrally connected therewith, and slidably mounted in holes 64 and 65, respectively, in top and bottomV walls 66 and 67 integrally connected with rear wall 68. The walls 66, 67 and68 have their sides integrally 'formed with sides 66 ot' casing 35. rlhe frontedges of walls 66 and 67 are integrally connected with front 69 ot the casing, whereby compartment lT() is :termed with inlet- 32, of chamber 34, communicating with the compartment;

The heads 58 and 59, respectively, are positioned as shown in. Fig. 6, with the outer edges of plates 60 andGl in close engagement with seats 71 and 72 of walls 66 and f 67" only when the pump is not operating.

When the valve is partly open, but not fully, a relative-small quantity ot' water is adapted to iiow from main drain outlet 26.

However, when the heads 58 and 59 are positioned shown in Fig. 7, with plates 60and 61 disengaged from seats 71 and 72, the water of the tulllcapacity of pump 21 is adapted to flow from basin 1, through drain pipe 26, pipe 25, valve 30, compartment 70, chamber 34 and thence into pump 31, through pipe 73 which connects the pump with outlet 740i chamber 34 of casing 35. The plate 75, suitably secured, to casing 35, prevents the water from escaping rom'chamber 33 through hole 33 in the easing. i l.

When the level ot'the surface of water 9, in basin 1, is sufficiently high to permit its flow over side 11' and into scum gutter 8, the water` is adapted to flow from the scum gutter through pipe 24, valve 29, casing 35 and pipe 73 into pump 21, `whereby the surface of the water which flows into the scum gutter is conserved by beingtiltered and returned into basin 1, as previously explained. Inasmuch as the water tlows from basin` 1 into scum gutter 8 with practically no water-` head, an insuliicient quantity of water would How` from the scum gutter into pump 21, if pipe 24 were connectcd'directly with pipe 25. Therefore, the control 36 is utilized to restrict ork retard the How ot the watery fromV main drain outlet 26 to permit the water to flow from the scum gutter into the pump throughpipe 73 which also communicates with pipe 25 and outlet 26.

The` control 36 is 'positioned below the level of water 9, so that float 49 approximately is on a level determined by subtracting, from theL level ofthe water 9, the distance equal to the respective waterhead caused by the restriction or resistance of the pipes and inlets to the flow of the water fromthe, scum gutter to casing 35, and also in consideration of the respective quantities of water, over` a givenperiod, desired to be received into pump 21 Yfrom each of the scum gutter andina-in drain outlet sources, whereby float 49 being adapted to operate valve head 57, the quantity tlow of the water from the main drain outlet is automatically restricted or retarded proportional to the level of the surface ofthe water in basin 1, with relation to outer side 11 of the scum gutter.

lllhen'the float, which is-in reservoir 43, is positioned to partly stop the flow of' the water Jfrom pipe 25, the result` is caused by, the level of the surface of the water in the basin being sufficiently high that a quantity of water is flowing ,trom the scum gutter, whereby the water communicated to the reS- ervoir causes the float to rise in reservoir 43, thereby operating valve head 57'so that only the required quantity oi water, will How from the main drain outlet. y

For example, if the level of. the surface of the water in basin 1 is near or belowl side 11 oi' the scum gutter whereby less than, the required quantity of water, or nonefiiows, into the scum gutter, or if the valve 29.is manually closed, the level o'l' the water in the reservoir is lowered, thereby lowering, float 49 which causes plates 60 and 61 tor disengage from seats 71S and4 72; and permits pump 21 to draw its capacity ot water from the main drain outlet, until the level` oi the water in the basin rises which causes the float to rise, thereby operating valve head 57 with relation to the valve seats 71 and 72 and retards the flow of the water from outlet 26.

It, for illustration, it is desiredthatOC/'b of the water received by the pump 21 shall normally flow from the scum gutter, and 50% from the main drain outlet, then the scum gutter piping system is designed so that when 50% ot the flow of water. tothe pump is from the scum gutter` source,.tl1e restrictions or resistance to the flow Jfrom the outlet is equivalent to the difference in the waterheads of the two sources. words, the water from the scum-.gutter flows unobstructedly throughthe control, but4 the quantity of water overa given period which flows through the control from drain 26.is

controlled and dependent upon the quantity.

of water, over a given period,which flows through the control from the, scum-gutter source. And, if no water is beingAv received by the control from the seumfgutter, then the full capacity of the pump is received through the drain `2.6.-` But. a, predetermined quantityV of water, proportionalto the quantity being received from drain 26, is per- In .otherA mitted to flow through lthe control from the scum gutter. The limit of the proportional flow of water from the scum-gutter to the pump is controlled by the water head s the casing 25 and the mechanism described.`

The pipes 76 and 77,V having usual gate valves 78 and 79 connec-ted therewith, respectively are connected with the water source of supply and the sewer to provide for draining the basin of the pool and filling it with a fresh supply.

It is understood that pipe 24 may have connection with suitable outlets in the walls of a swimming-pool basin, as the important purpose of the pipe 24 is to drain the surface water into the pump,` irrespective whether or not the scum gutter 8 or other outlets are utilized for the purpose.

The control 36 may be made of any size, and constructed of any materials deemed convenient and suitable for a device of this character, and while I have illustrated and described a form of construction, and arrangement of parts found desirable in materializing the invention, I wish to include in this application all mechanical equivalents and substitutions and the variety of uses that `may fairly be considered to come within the'scope of the purview of the invention, as defined in the claims;
